英文摘要	Conference Name:4th International Conference on Materials Science and Information Technology, MSIT 2014. Conference Address: Tianjin, China. Time:June 14, 2014 - June 15, 2014.; Computer Science and Electronic Technology; Inst. of Mechatronics Eng., Tianjin Univ. of Technol. and Educ.; Trans Tech Publications inc.; Ultra-low-bit-rate speech coding algorithm was in great demand for many fields such as underwater speech communications. Underwater speech communication for middle-long distance has the characteristics of narrow bandwidth as well as low transmission rate, which makes the underwater speech communication much difficult. Ultra-low-bit-rate speech coding algorithm plays an important role on this occasion. More over, it will be more flexible for the underwater speech communication system if the speech coding algorithm has an embedded structure. The paper introduced the principle of an embedded speech coding algorithm with dual rates at both 300bps and 400bps based on the enhanced mixed excitation linear prediction model. The results show that this embedded ultra-low-bit-rate speech coding algorithm has satisfactory quality under both DRT and MOS test. ? (2014) Trans Tech Publications, Switzerland.
